如何在Java中使用themoviedb.org api

问题描述：

我正在使用themovidedb.org api来获取Java程序中的电影信息。如何在Java中使用themoviedb.org api

这是我使用的链接与themovidedb.org我的应用程序的功能：

 url = new URL("http://api.themoviedb.org/3/movie/550?api_key={MY_API_KEY}"); 
     HttpURLConnection con = (HttpURLConnection) url.openConnection(); 

     con.setDoOutput(true); 
     con.setRequestMethod("GET"); 
     con.setRequestProperty("Content-Type", "application/json"); 

     BufferedReader br = new BufferedReader(new InputStreamReader((con.getInputStream()))); 

     String output; 
     System.out.println("Output from Server .... \n"); 
     while ((output = br.readLine()) != null) { 
      System.out.println(output); 
     }

这是在控制台响应：

{"adult":false,"backdrop_path":"/87hTDiay2N2qWyX4Ds7ybXi9h8I.jpg","belongs_to_collection":null,"budget":63000000,"genres":[{"id":18,"name":"Drama"}],"homepage":"http://www.foxmovies.com/movies/fight-club","id":550,"imdb_id":"tt0137523","original_language":"en","original_title":"Fight Club","overview":"A ticking-time-bomb insomniac and a slippery soap salesman channel primal male aggression into a shocking new form of therapy.

我如何解析响应获取任何属性（例如：'original_title'，'relase-date'）并在代码中使用它？

存在一种将程序链接到数据库的替代方法（例如使用WebResource类）？

你还是使用现有的Java包装周围的HTTP API像https://www.themoviedb.org提到的那些/ documentation/api/wrappers-libraries - 如果你想遵循你的方法，你需要一个json解析器（或写一个）。 PS：'setDoOutput（true）;'是'POST'，'PUT'请求和'Content-Type'只在请求或回复包含内容主体时相关。你可能想在你的请求中设置Accept：application/json，告诉服务器你想要什么类型。 – zapl

结果使用JSON格式化。有很多Java库可以用来解析它。 Java EE的built-in method使用JsonObject。

JsonReader rdr = Json.createReader(con.getInputStream()); 
JsonObject obj = rdr.readObject(); 
String title = obj.getString("original_title");

在Android上，您有JSONObject。

StringBuilder responseStrBuilder = new StringBuilder(); 

String inputStr; 
while ((inputStr = br.readLine()) != null) 
    responseStrBuilder.append(inputStr); 
JSONObject obj = new JSONObject(responseStrBuilder.toString()); 
String title = obj.getString("original_title");

还有很多其他库能够做到这一点，如果你有其他要求。也有一些HTTP库，可以很容易地获得JSON像Volley为Android：

JsonObjectRequest jsObjRequest = new JsonObjectRequest 
     (Request.Method.GET, "http://api.themoviedb.org/3/movie/550?api_key={MY_API_KEY}", null, new Response.Listener<JSONObject>() { 

    @Override 
    public void onResponse(JSONObject response) { 
     System.out("title: " + response.getString("original_title")); 
    } 
}, new Response.ErrorListener() { 

    @Override 
    public void onErrorResponse(VolleyError error) { 
     // TODO Auto-generated method stub 

    } 
});
